Not sure I want to say this doesnt work without more uses but it didnt stop the leaking of a small pipe. Its also very hard to get the protective covering off. Make sure you have someone with you that has some finger nails.

This is essential for any home owner, RV owner, Trailer, DIY person, Repairman etc. This is great tape with lots of adhesion. If you dont know about Butyl Type then you need to look it up. It’s sticky and gets into a space to seal it up good.

I obtained this tape to fix a problem with an old fiberglass shower in the basement. The shower still works fine, but there is a crack in the base where it meets the shower basin, and thats been causing a water problem on the floor. I got the 4 inch tape and applied it. Presto, no more leaks! The tape is holding up like a champ, too. I mean to eventually replace this shower stall, but honestly, the way this tape is sticking to the shower wall, I dont have to be in a rush with that new shower purchase! Highly recommend!

This is a great product for small roof leaks. It’s a must have in your home. Definitely keeps water out. I recommend this product for the quality and price.

This tape is fantastic - sticky, wide, and waterproofing. Too bad I didnt have it two weeks ago when the PODS container I rented let rain in all around the edges where the sealant has dissolved, leaving the wood floor (and some of my boxes) wet all around the container edges. Happy to have this in the tool kit for the next time its needed. Definitely dont stick it anywhere youd want to remove it, that would not be easy and youd lose/mess up the surface material it was adhered to most likely.

This tape is so cool! I didnt know you can even get anything like this. I had a leak on a metal roof and put this on and it stopped it! It is definitely water proof because no water had made it in where I put it. I would definitely use this again should the need arise.

The tape is very sticky. I needed it to patch a crack in a sky light cover and so far it is doing the job that I need it to do.

This is excellent tape for all sorts of repairs. Its a high quality heavy duty thick tape that I think will last a good long time. It is water proof and sticks very very well. If you have a large area to cover this 4 inch wide roll is a nice size. You get a full 16 feet so I think its a good deal for what you get. I used the 2 inch wide to cover a joint between two walls in a shower in an attempt to identify a leak and it worked great. Stuck well and stopped the leaking until I can get it permanently repaired. It would also be great for tent repairs if something happens while out camping. So many uses. I do wish it came in other colors but thats just the girl in me...lol

I have to say this is the best tape I have came across so far to stop leaks. Tried a few others but they were not as good. Obviously, this tape is not going to stop a sinking ship, lol, but it will stop a leak better than any of my previous tapes for sure. So I did my usual test and this one came out better than all the others. As shown in the attached pictures, I poked a hole into the bottom of a plastic cup, and while the water was leaking out, I patched a small piece, less than a square inch, of this tape on and the leak was, almost stopped immedately. Then I pressed the tape into the leaky hole a little harder and around to make sure I pushed out all the air pockets, I was amazed to see that the water stopped leaking all together. That was the first time seeing a tape actually stopped leaking water like that for me. Albeit, it was just a small leak and I only used a small sample piece of tape to test with. Once the leak stopped completely, I filled up the leaking cup with more water, left it alone overnight and woke up to see the cup was still full, very impressive. All the tapes I tested in the past would have failed within the first 10 minutes. However, as soon as I moved the cup around and the water was moving inside, I could feel a little moisture leaking around the bottom of the patched tape. I then pressed the tape in a little more as if to push out more air pockets and the leak stopped again. One other thing to point out, this may be due to me not making a clean flat cut when poking the hole, I made a little dent around the hole so it was not as flat for the tape to stick onto fully, would have worked better if it was more flat. So I am not sure how much pressure this tape can withstand per inch, buit still, I am impressed with this tape, very sticky and tacky like chewing gums but a lot more stickier. It will leave a little residue on the hands after touching it by the way. Bottom line, this is a great tape to keep around the house just in case you have a leak here and there. It also works well on stone as well, I have also attached a picture showing a small piece sticking on a somewhat uncleaned limestone :). Very strong and durable tapes as well as very useful, can be applied on different surfaces too. I can see that this will work great for tarps or shed roofs too.

This tape sticks like crazy and is totally waterproof. Used on an inflatable kiddie pool and it totally sealed it.
